ltle it known that l, llllARlUS llovitriin. oitimen of the United motes, residing at UiUlQl' lieltl, county of Esmeralda, tltete oil". hl evodu.

- here invented certain ucw ;u1d useful improvements in Coinhustionlfiutginee, whereof the following is o specification.

This invention relates to internal oomljiuetiou engines, and its object is to improve the construction and operation at the vol-res: of such engines.

lift. its main features the e valve in the form of o. cylindrical collur, ttllfl in the accessories thereof by which he stone is mettle operative;

in eotryiug out thevinvention apply the cylindrical colhir velve, or annulus, egeiiiet invention cimsists 'the surtece of the engine cylinder, either upon the inside or outside thereof or inter- .uietliote to those positions, and preferably near the top of the some. The elive time eeetS upon'the circumference oil" the cyltu (ler. The valve has, preferehly, hut one port and the cylinder has two ports. flit oroper intervals the valve port is opposite, port, to zithiiit the chutge into the cylinder.. or with the exhaust port, to permit the cu mieioi of the burnt gases, or with the hliroit well of the circumference, when the power cud compression strokes tithe place. f valve is rotated, by euitoiole connections. item the engine shaft, so that the engine goes through its cycle of suction, compree eion, combustion and exhaust.

lm these several tigureszi l is the cylinder of the engine, and 2 the collar valve, applied to the upper part thereof. The valvev is housed in u cavity 3 in the end ol. the cylinder, which may he formed by coring. in the casting thereof, in which case the sides ofthc cavity are integral with the cylinder, as elaown-iii Fig 2; or may be otherwise formed. The cavity may he (fltlw'tlll. zit the totuhythe cjy'liuderend t. llltttl the lower edge of the valve are out or etched gear teeth 5, with whit-hem mo e the pinion (3 by which the valve is 1'0.

valve may he cost oi steel, and may he hurl cried.

The pinion ti is mounted on. on arbor 12, which rotates in bearings 13 and l t, upon the cylinder end is connected direct with the main shalt dud rotatedtherefrom.

15 lo the sperlr. plug, for igniting" the charge.

16 are tubes leading from the oil reservoir which deliver lubricant through opciiings ll', shown in Figs. 2, 9 and 10, tot-he top edge of the valve, whence it may pass through. channels 18 to the lower edge thereof, as shown in Figs. 5, 6, 7, and 8,

till

In some cases it may be desirable to provide the valve with knife edges, to more perfectly center it, and reduce wear. Such knife'edges I have shown at- 19 and 20, in Fig. 9. Also I have shown one such knife edge in Figs. 2, 5, 6 and 7.

Where the valve is unhoused, as in the form shown in Figs. 9 and 11, the operating teeth 5, may be out upon a rib 21, projecting from the body of the valve.

Where the valve is applied interiorly, as shown in Figs. 10 and 12, it is best operated by a stem 22, projecting into the cylinder from the end thereof, and engaging spokes 23 attached to the valve. In this case the pinion 6 engages an auxiliary pinion 24 upon the stem 22, instead of engaging teeth on the body of the valve.

It is believed that the operation of the valve is sufliciently obvious from the foregoing description of its structure, and that further description would obscure rather than enlighten.

Having thus described my invention, and an embodiment of it, in the full, clear and exact terms required by law, and knowing ,that it comprises novel, useful and valuable improvements in the art to which it pertains, I here state that I do not wish to be limited to the precise construction and arrangement of the several parts, as herein set forth, as the same may be variously modified by a skilled mechanic'within the scope of the appended claims without departing from the spirit of the invention.

' What I claim and desire to secure by Letters Patent of the United States, is the following, to wit:-

1. In an internal combustion engine, a casing having a V-shaped groove, a cylindrical collar valve having-a V-shaped edge engaging said groove.

2. In an internal combustion engine, a cylindrical collar valve-having a V-shaped edge, a casing for said valve having an oil channel engaging said V-shaped edge and said valve.

3. In an internal combustion engine, a

cylindrical collar valve having a knife edge, in combination with a cylinder having a corresponding groove for said knife edge and means to rotate said valve.

4. In an internal combustion engine, a cylindrical collar valve fitted and seated upon the exterior surface of the cylinder, said valve being open at its ends and means to continuously center said collar valve.

5..In an internal combustion engine, a cylindrical collar valve havingknife edges, said edges engaging corresponding grooves upon the cylinder, in combination with said cylinder and means for rotating said valve.

6. In an internal combustion engine, a cylindrical collar valve, in combination with the cylinder thereof, said valve mounted upon a surface of said cylinder. having V- shaped means adapted to centralize said valve.

7 In an internal combustion engine, a cylinder having an annular cavity and a lubricating opening oplposite said cavity, in

combination with a cy indrical collar valve, in said cavity provided with a knife edge opposite said opening permitting thereby uniform oiling of its bearing faces.

8. In an internal combustion'engine, a

cylindrical collar valve, mounted upon the exterior face of the engine cylinder, and having a V-shaped edge corresponding with a V-shaped seat upon the cylinder adapted to hold said collar valve in perpendicular position.

In testimony that I claim the foregoing I have hereto set In hand in the presence of two witnesses, this 16th day of October,

MARIUS DUVAIL.
